3 Claims.

This invention relates to transporting equipment for molten metal usedin foundry plants, and this application is a division of an appli-Divided and this application May 26, 443,794

cation for United States patent on Foundry plainstsi flied by me July 9,1941, Serial Number 40 The principal objects of the invention are toprovide equipment which may be manufactured at a low cost but which iscomparatively safe in use, and equipment including ladies which may becompactly stored and transported when not being used for filling molds,and detachable bails and operating or guiding handles which may beplaced in operative relation to the ladies when their use is required.Thus a ladle may receive molten metal at the melting furnace and bemoved on a conveyor in rather restricted quarters, and equipped with abail and guiding handle means at or adjacent the pouring station forlifting and guiding the ladle to a position over the sprue holes orgates of the mold.

Other objects and advantages of the invention will appear in thefollowing detailed description, taken in connection with theaccompanying drawing, forming a part of this specification, and in whichdrawing- Figure 1 is a side elevation of transporting equipmentconstructed according to the present invention, a part being broken awayand shown in section to illustrate details.

Figure 2 is an end elevation oi. the same.

Figure 3 is a plan of the detachable handle or guiding means.

Figure 4 is a side elevation of an eye part of the bail.

Figure 5 is a vertical section on the line 5-5 of Figure 4.

Figure 8 is a side elevation of a bar forming a part of the bail.

b fligure 7 is a side elevation of an arm of the Figure 8 is an endelevation of the arm.

The equipment comprises a ladle 9, a bail l0 and handle means ildetachable with respect thereto, and means I! for releasably holding thehandle means on the ladle.

The ladle is preferably, altho not necessarily, of the type shown in myco-pending application for United States patent filed May 20, 1942,Serial Number 443,795, which is adapted to permit the molten metal toflow from the bottom of the ladle. It includes an invertedfrusto-conicai wall portion I3 and diametrically disposed laterallyextending trunnions ll each having a reing a body part it and a head ll.These trunnions have a dual purpose-to cooperate with the detachablebail and to support the means it, as shown in Figures 1 and 2.

The ball is preferably made mainly of stock or easily procurablematerial such as a ring it, horizontal bars I9, bolts 20 having nuts 2!,and bolts 22 having nuts 23. The ring I? has a segmental spacer 24welded to it, as shown in Figures 4 and 5, to fill approximatelytwo-thirds of the opening of the ring, leaving an eye 25 above thespacer for a hook 26 of hoist mechanism, not shown in the drawing. Toaccommodate the shanks of bolts 20, used to secure the ring is andspacer 24 to the central portions of the bars i8, the bars are providedwith transverse openings 21 and the spacer 24 with transverse openings28. This assembly constitutes a yoke 29 to the end portions of which areplvotaily connected arms 30, preferably arcuate in shape, so they may beswung into position and connected to the trunnions N, or folded inwardlybeneath the ring l8 to render the bail compact when being stored'ortransported. Each arm is preferably made to comprise a body part 3i anda lower terminal portion 32. The body part is preferably of channelshape comprising a. web 33 and flanges 34. The upper ends of the flangesare provided with aligned openings 35 for the shanks of bolts 22, whichlatter are accommodated in aligned openings 36 in the end portions ofbars ll. Each terminal portion 32 has a keyhole slot 31, the upperportion 38 of which is of a size to freely receive the head I1 and thelower restricted portion 39 to snugly receive the reduced portion I! ofits respective trunnion it.

Referring now to the handle means ii, it comprises a ring it made tosnugly engage the tapered wall It of the ladle, and diametricallydisposed lateral arms ti extending therefrom, provided with hand gripportions 42. The ring 40 is preferably of inverted frustc-conical shape,the inner taper 48 corresponding to the taper of wall portion itsomewhat spaced below the trunnions I 4 and above the bottom of theladle,

so as to have surface to surface contact with duced portion i5intermediate its ends, provid- 68 the ladle when the ring is raised intocontact with same and so as to lit in a horizontal positionsymmetrically with respect to the axis or the ladle.

The means I! in the example shown comprises lengths of chains 44preferably having rings or handles 45 at their end portions, the otherends being secured as at 48 to the trunnions I. When the handle means iiis in place on the ladle, intermediate portions of the chains may bequickly wrapped around the arms ll to hold the handle means I i inplace.

As an example of use or the transporting equipment for molten metal, theladies with the bails and handle means detached, may be charged.

at the melting furnace and moved on any suitable conveyor to the pouringstation, where they may be equipped with bails l0, lifted and handlemeans ll applied. At the pouring station they may be used to assist inplacing the ladies over the molds, and when empty, the balls and handlemeans may be detached and the ladies returned to the melting furnace ona conveyor to be recharged, or to storage space it no longer needed forthat particular casting operation.

I claim:

I i. In transporting equipment for molten metal, the combination of aladle provided with oppositely extending, laterally disposed trunnions,and handle means below said trunnions, detachably carried by the ladle,including a body portion embracing the wall of the ladle, op-

positely extending laterally disposed arms on said body provided withenlarged hand grip portions at their free ends, and flexible memberscarried by said trunnions with the intermediate portions thereof adaptedto be wrapped around said arms between said body portions and hand gripportions, to hold said body in embracing relation to the ladle with thefree ends of said flexible members depend ing from said arms.

2. In transporting equipment for molten metal, the combination of aladle provided with oppositely extending, laterally disposed trunnions,and a detachable bail for the ladle including a yoke comprising a pairof paralleling bars, a spacer between with the intermediate portions ofsaid bars, provided with a segmental portion, a ring, of less thicknessthan said spacer, extending about the periphery of the segmental portionof said spacer and above said spacer, and means securing said bars tosaid spacer, said ball also including a pair of arms, depending fromopposite ends of said bars, provided with means at their lower ends fordetachable connection with said trunnions.

3. In transporting equipment for molten metal, the combination of aladle provided with oppositely extending, laterally disposed trunnions;a bail for th ladle pivotally connected to said 20 trunnions; handlemeans including a body portion detachably embracing the wall of theladle below said trunnions, and oppositely extending, laterally disposedarms carried by said body portion, said arms located one below each oisaid as trunnions; and means detachably suspending said handle meansfrom said trunnions, including a chain for each companion trunnion andarm, each chain having its upper end portion secured to its respectivetrunnion and its inter- 30 mediate portion wrapped about its respectivearm, with a free end portion of the chain de-
